matching a driver with Led strips

Might work out cheaper on two meanwell 320h-24s , bit more power too, though don't know what area your lighting

Yet to build a strip light.

Is it true a split offers fault tolerance in the event of driver failure? Wired so only half the strips go dead.

I've read where some keep a spare driver on hand.

Certainly keeps half the light on while you get a replacement.

I think I'll go with 2x HLG-320H-C1750B per 5' x 5' fixture and wire them in series.

Double check the data sheets. At test current it would work but at 1750ma it could be over the drivers available voltage.
I don't think they show a nice graph so you can see the fV exactly.
 
consider that your efficiency will be lower then the stated 192 lpw at 1750mA.
Doubble the stripcount,then you should be safe, always 2 strips in parallel, then in series.
Sammies exel when driven low, should get you in the 200lpw range.

Or go with the bridgelux eb3, they state 200 lpw at 700mA, more strips, more leds, better coverage also.
 
When you get down to it, the price per W of Meanwell drivers is really pretty close to standard, regardless of size. So basically, it's a matter of wiring preference.

The forward voltage is 22.4 at 8 strips per driver is 179.2v. Max voltage on the driver is 183

183 volts/8 strips = each strip gets a maximum of 22.873 volts, right? I'm estimating the HLG-320H-1750 will top out at about 1600 ma into these strips due to hitting the voltage limit. I could be wrong due to using a hand drawing of a non linear graph with only 3 data points.
 
That HLG-320H-C1750(A or AB) has been tested to make 2.02A, strips would need 183.2V. Probably enough wiggleroom in the drivers' voltage that it'll light up at that current just fine.
